To pretend means to act as if something is true when you know it isn't. When you pretend to be a pirate during playtime, you're not actually sailing the seas or searching for treasure, but you're acting like you are. When a younger sibling pretends to be asleep to avoid bedtime, they're deliberately creating a false appearance.

Pretending shows up everywhere in childhood. Kids pretend to be astronauts, teachers, or dragons. Actors pretend to be characters in movies and plays. This kind of pretending is called make-believe, and it's how children explore ideas and practice for real life.

But pretending can also mean something less innocent. If someone pretends to be your friend but talks behind your back, or pretends to understand the math lesson when they're actually confused, they're being dishonest with themselves or others. When you pretend not to notice something embarrassing, you're acting like you didn't see it to spare someone's feelings.

The word suggests a deliberate choice to create an appearance that differs from reality. Whether that's imaginative play, protective kindness, or outright deception depends on the situation and the pretender's intentions.
